1 'i'ilaim. (Cl. 83ill 1 b shelled corn with another ingredientor other ingredients to produce a prepared feed;

More specifically, the invention contemplates an apparatus of the above kind including a corn sheller, a hammer mill or grinder, and means for feeding the shelled corn from the corn sheller, along with another ingredient or other ingredients, such as-oats, wheat, and/or roughage, to the mill or grinder and in proper proportions for being ground and mixed by said mill or grinder to produce a prepared feed.

Stillmore specifically, the invention contemplates an apparatus of the above kind which is as nearly continuous and automatic in action as possible, whereby the prepared feed may be quickly and economically produced with the expenditure of a minimum amount of manual labor and by an organized mechanism whose successful operation requires little attention or special skill. Still another object of the present invention is to provide an apparatus of the above kind involving a comparatively simple and emcient modification of a conventional portable feed grinding apparatus, whereby the single source of power utilized to operate the mill or grinder and other mechanism of such conventional apparatus is also utilized to operate the'corn sheller and means for conveying the shelled corn fromsuch corn sheller to the mill or grinder or its feeder.

35 With the above general objects in view, and

. others that will become apparent as the nature of the invention is better understood, the inven tion consists in. the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings, and claimed. y

In the drawings, wherein like reference char 'acters indicate'similar parts throughout the several views: 4

Figure 1 is a fragmentary top plan view of an apparatus embodying the present invention;

Figure'Z is a side elevational view thereof.

, Figure 3 is a transverse vertical section on-lin ,3-3 of Figure l; and

50 Figure 4 is a fragmentary vertical longitudinal section on line 44 of Figure 1.

Referring more in'detail to the drawings, 5 indicates the supporting frame of; the apparatus,

' 3 which may consist of the rear portion of the chassis frame of a motor'truck. Mounted at the rear oi the frame t near one side is the usual conventional hammer mill or grinder t of the type illustrated in the U. S. Patent to T. C. Alfred No. 1,829,325, dated October 27, 1931, said mill or grinder having a suitable rearwardly extending b feeder l which may be oi any well known or preferred construction, but which is shown as embodying a pair of endless carriers t for conveying the oats, roughage or the like'into the top of the grinder or mill t. its is also usual in portable 1W apparatus of this kind, an internal combustion engine 9 is mounted on the frame 5 transversely of the latter and in front of the grinder t and operatively connected by a belt gearing illwith the mill or grinder t at the outer side of the latterfor driving the same. This type of mill or grinder t has a bottom outlet chamber open at the inner side and directly communicating with the casing of a blower Ill bolted against the inner side of the mill or grinder casing. The fan of blower ii is m carried by a shaft ii that extends into the outlet chamber of the grinder t where it is equipped with an agitator, asand for the purpose clearly set forth in the Alfred'patent mentioned above? The rotor drive shaft of the grinder projects at the inner side of the casing of the latter where it isprovided with a pulley it operatively connected with the blower shaft it by a belt gearing.

it including a belt tightener it. Mounted on the rear of the frame 5 at the inner side of feeder i is a centrifugal separator it into which the out let duct or conduit ll of blower iivopens tangentially in the usual manner. It will be understood thatthe blower conveys the ground and mixed material to the separator it, the air and lighter foreign material being discharged through the top outlet it of the separator it, and the heavier valuable material settling to the bot= tom ,of the separator, from whence it may be selectively discharged through either of the two 40 outlet spouts it into suitable receptacles for storage or transportation. The construction asthus far described is more or less conventional andwell known in the art.

In accordance with the present invention,

general type illustrated in thel Uv. Patent to 55 I mount a corn sheller it of any well known or of the belt tightener IS. A suitable bracket 25 is mounted upon theinner bearing for the rotor shaft of grinder 6 to form a mounting for pulley 2| and for the arm of belt tightener 23.

I further mount upon the frame 5 a vertical elevator 26 which is arranged directly at the rear side of corn sheller 20, and which preferably includes, a casing, in'which is arranged to travel an endless carrier 21 provided with flights or paddles 28. The endless carrier 21 extends about sprocket wheels on head and foot shafts respectively journaled at the top and bottom of the elevator casing, the-head shaft projecting at the inner side of the elevator casing'and'equipped with a large pulley 29 operatively connected by a driving belt 30 with a further small pulley 3| fixed on the shaft of pulley 2|. It will thus be seen that in this way the endless carrier of the elevator is driven by a chain of belt gearing from the rotor shaft of mill or grinder 6.

The corn sheller 2ll is provided with a bottom inclined discharge spout 32 for the shelled cornwhose lower end communicates with the bottom of the casing of elevator 26 through the outer side of the latter, the spout 32 having a removable section 33 at the side inlet opening of the casing of elevator 26, so as to facilitate access to the internal bearings for the foot shaft of elevator 26, for lubrication or other purposes. I It will thus be seen that the shelled corn from the sheller 20 is delivered by gravity through the spout '32 into the lower end of the elevator 26 from whence it is elevated by the carrier 21 to the top of said elevator where the latter is provided with an inclined discharge spout 34 that extends inwardly and rearwardly to a point adjacent the inner side of feeder I so as to discharge the shelled corn into said feeder for beingdelivered along with the other ingredient or ingredients to the mill or grinder 6 forbeing mixed and ground to produce the prepared feed. It will be noted that the con-- struction is comparatively compact and simple and provides an arrangement whereby the several operations may be efficiently carried out in a continuous and substantiallyautomatic manner, the apparatus requiring comparatively little attention or skill for its successful use. The corn sheller 20 is provided with the usual feed hopper 3! to receive the ears of corn to be shelled, and the other ingredientsare suitably discharged into the feeder I. From the foregoing description, it 5 will'be seen that the-com will be automatically shelled and the shelled corn will be automatically delivered along with the other ingredients to the mill or grinder 8, for being effectively mixed and ground to produce a prepared feed mixture which 10 is subsequentlycleaned of foreign matter in the separator I 6 in producing the final product or prepared feed which is discharged into suitable containers through the spouts M. It will be particularly noted that my invention provides a 16 highly eflicient apparatus for achieving the stated objects of such invention. Minor changes in the specific construction illustrated and described are contemplated within the spirit and scope of the invention as claimed.

What I claim as new is:

An apparatus for the manufacture of prepared feeds, comprising an elevated supporting frame, a grinding mill mounted on said frame at the rear and adjacent one side of the latter, an inclined 5 feeder extending rearwardly ofsaid frame and a arranged to feed certain feed material forwardly and upwardly from a point adjacent the 'ground into the top of said grinding mill, a motor mounted transversely of and on the frame forwardly of 39 the grinder and operatively connected to the latter for driving the same, a corn sheller mounted upon the frame beside the grinder and rearwardly of the motor, an elevator mounted upon the frame rearwardly of the corn sheller, driving connections between said grinder and the head shaft of said elevator, further driving connections between said grinder and said corn sheller, means to convey the shelled corn from the corn sheller to the bottom of the elevator, a rearwardly inclined and inwardly extending discharge spout for directing the shelled corn from the top of the elevator onto said feeder to be supplied with said certain feed material to said grinder, a centrifugal separator mounted in an elevated position on' and arranged rearwardly of the frame beside said feeder for discharging the prepared feed into suitable containers positioned beneath said separator, a blower mounted 'on the inner side of the grinder and forming part-*of means for .conveying the ground and mixed ingredients from the grinder to the separator, and a'driving connection between the grinder.and said. blower.
